Yuncheng Salt

Yuncheng Salt

　　Produced in Yuncheng, Shanxi. The main resources in the salt lake—sodium sulfate, sodium chloride, and magnesium sulfate—have a total reserves of over 83.7 million tons. There are also abundant deposits of various rare elements such as bromine, calcium, iodine, potassium, boron, as well as lithium, barium, strontium, gallium, rubidium, and more. In addition, there is a type of nitre crust that coexists with the salt, known as blödite, which is a double salt primarily composed of sodium sulfate and magnesium sulfate. It has a thickness of 2–4 meters, with reserves of over 16 million tons, and the mineral deposit is exposed on the surface. This is a uniquely valuable resource formed through thousands of years of salt production by previous generations.
